Digital truck scale is used more and more widely, but in the use of electronic truck scale, small errors in weighing equipment will inevitably occur. Anyone who knows about the allowable error range of digital truck scale knows that the error of digital truck scale is much larger than that of unattended truck scale. What is the reasonable range of the error of the digital truck scale?
Before understanding the error standard of electronic truck scale, we should first understand some basic concepts: division value (e): for example, the weighbridge is 60 tons, while 20KG is the starting value, and 20KG is the division value of the weighbridge. Of course, in actual use, the 60KG weighbridge is often adjusted to the 10KG graduation value. Dividing number (n): dividing the weighing peak value (full scale) by the dividing value is the dividing number. For example, for a weighbridge with a full scale of 80 tons, the division value is 20KG, and the division value of the weighbridge here is 80000KG/20KG=4000.
The National Bureau of Metrology has made specific provisions on the allowable error range of digital truck scale: the heavier the weight value is, the greater the allowable error value is, but the error should be within plus or minus three standard ranges. According to the above description, we can roughly judge that the larger the weight value is, the larger the allowable error value is!
